Hmm, I think it might be better to separate this from the dump_on_oops. How about a ftrace_default_tracer parameter?
If one is defined, it is activated as soon as it is initialized. This way we decouple the dump_on_oops, which we may not always want, and a way to start tracers before the switch to user space.
